[{"name":"SP-240023","title":"TS 26.251-100 - Codec for Immersive Voice and Audio Services - C code (fixed-point)","source":"SA WG4","contact":"Antoine Burckard","contact-id":97796,"tdoctype":"draft TS","for":"Information","abstract":"Abstract of document: The codec for Immersive Voice and Audio Services (IVAS) is part of a framework comprising besides encoder and decoder, renderer associated with the support of stereo and immersive audio formats. The IVAS codec is an extension of the 3GPP Enhanced Voice Services (EVS) codec; it provides full and bit exact EVS codec functionality for mono speech\/audio signal input. On top of that the IVAS codec is optimized for encoding and decoding of stereo and immersive audio formats, Immersive audio formats comprise multi-channel audio (5.1, 5.1.2, 5.1.4, 7.1, 7.1.4 setups), scene-based audio (Ambisonics up to order 3), metadata-assisted spatial audio (MASA), and object-based audio (Independent Stream with Metadata (ISM) up to 4 ISMs). In addition, the following combined immersive audio formats are supported: object-based audio with scene-based audio (OSBA, up to 4 ISMs with Ambisonics) and object-based audio with metadata-assisted spatial audio (OMASA, up to 4 ISMs with MASA). Rendering between many of the formats is supported, including binaural rendering for headphone reproduction with head-tracking and rendering to various loudspeaker configurations. The present technical specification TS26.251 (Codec for Immersive Voice and Audio Services; C code (fixed-point)) contains: - Specification of C code structure - Specification of file formats as used by the IVAS codec. Changes since last presentation to SA Meeting: First presentation to SA Meeting. Outstanding Issues: Electronic attachment with fixed-point C code missing. Contentious Issues: None.","secretary_remarks":"Noted","agenda_item_sort_order":81,"ainumber":"6.9.4","ainame":"SA WG4 Specifications for Information","tdoc_agenda_sort_order":11860,"status":"noted","reservation_date":"2024-02-27 12:56:57","uploaded":"2024-03-01 17:33:57","revisionof":"","revisedto":"","release":"Rel-18","crspec":26.251,"crspecversion":"1.0.0","workitem":[{"winame":"IVAS_Codec"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_SA\/TSG_SA\/TSGS_103_Maastricht_2024-03\/Docs\/SP-240023.zip","group":"SP","meeting":"SP-103","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0},

It typically include a bidirectional conversational A\/V connection in addition to other non-real-time AR media for collaboration or communication between two or more users. To support the conversational AR services, this specification provides a set of media components, AR metadata, and media configuration for AR media processing in network.
